When tested with an XRF instrument (for repeated 30 second tests on each component) the Mikasa cup and saucer pictured here had the following readings:
White center of plate
- Lead (Pb): 69 +/- 15 ppm
- Barium (Ba): 383 +/- 56 ppm
- Zinc (Zn): 32,500 +/- 800 ppm
- Copper (Cu): 79+/- 38 ppm
- Iron (Fe): 461 +/- 123 ppm
- Vanadium (V): 1,046 +/- 225 ppm
- Titanium (Ti): 2,820 +/- 414 ppm
- Zirconium (Zr): 1,565 +/- 50 ppm
Floral area – blue and red:
- Lead (Pb): 18,900 +/- 500 ppm
- Cadmium (Cd): 167 +/- 17 ppm
- Barium (Ba): 476 +/- 78 ppm
- Tin (Sn): 199 +/- 26 ppm
- Zinc (Zn): 23,800 +/- 700 ppm
- Zirconium (Zr): 1,735 +/- 69 ppm
- Platinum (Pt): 357 +/- 155 ppm
- Cobalt (Co): 1,599 +/- 162 ppm
Floral area – yellow:
- Lead (Pb): 21,200 +/- 600 ppm
- Cadmium (Cd): 99 +/- 14 ppmBarium (Ba): 489 +/- 77 ppmAntimony (Sb): 77 +/- 27 ppmTin (Sn): 264 +/- 27 ppmZinc (Zn): 24,900 +/- 700 ppmIron (Fe): 453 +/- 143 ppmZirconium (Zr): 1,782 +/- 69 ppmPlatinum (Pt): 315 +/- 152 ppm
How much Lead is too much Lead?
The amount of Lead that is considered unsafe and illegal in a modern / newly manufactured item made and sold for use by children today is anything 90 ppm Lead or higher in the paint / glaze or coating and anything 100 ppm Lead or higher in the substrate. Dishes are not covered by this regulatory standard as they are not considered to be “an item intended for use by children” (however it is my professional opinion that they should be because children also use dishes!)
